(1)
Check 'O' seal compatibility with specific oil and possible solvent. Generally SS preferred.
Oils, Mineral

+
+
+
+
+
(1)
Also see gasoline & diesel oil. Possible problems with 'waxing' at high viscosities and low temperatures.
Possibility of hydrogen sulphide stress cracking in crude oils with steel (See NACE MR 0175)
Oils, Vegetable & Animal

+
+
+
+
